    摘要： A dynamic convergence apparatus of a simplified arrangement can reduce a distortion of a beam spot on a periphery of a picture screen and improve a focusing, wherein a parallel circuit of a high resistance value resistor (R) and a diode (D) is connected between low voltage side electrode plates (3), (4) and high voltage side electrode plates (1), (2) to which an anode voltage (HV) is applied, a capacitor (C) is formed by coating a conductive layer on the inside and outside of a tube envelope of a color CRT while glass of the tube envelope is used as a dielectric material, and a convergence voltage which results from adding a vertical parabolic wave voltage to the horizontal blanking period of a modulated voltage provided by amplitude-modulating a DC voltage very slightly lower than the anode voltage (HV) by horizontal and vertical parabolic waves is commonly supplied from one end side (outside of the tube envelope) of the capacitor (C) to the low voltage side electrode plates (3), (4).

    摘要： A cathode-ray tube apparatus (CRT) including a panel glass (4) which has been subjected to no external polishing, and an ultraviolet-curing resin layer (11) provided on the panel glass (4) and having a refractive index which differs from that of the panel glass (4) by not more than 0.8 %. The CRT further includes a light-transmitting film (12) provided on the resin layer. Also disclosed is a production method which enables a reduction in the weight of a CRT and an improvement in the explosion-proof performance, which have been demanded with the realization of large-sized CRTs and flat-panel CRTs, and which also makes it possible to produce such CRTs by a simplified process and at a reduced cost. The method also includes the use of a UV-transmissive vacuum container.
